Hannes Löschke replied to JP Mays's discussion How to find normals at intersection of a curve and surface?

"Since your curves are all lines, SCX (mathematical Surface-Line-Intersection) would be more appropriate and lines don't need to physically intersect the surface any more. Explode your BRep (since it is a kind of flat surface anyway) to get all…"

Andrew Kudless replied to JP Mays's discussion How to find normals at intersection of a curve and surface?

"JP, I think the problem is that the Surface CP will return the closest point on EVERY surface to each specific point from which you are searching. From this longer list, you need to find the point that has the smallest distance as this will…"

JP Mays replied to JP Mays's discussion How to find normals at intersection of a curve and surface?

"Chris, this is what I am trying to achieve, but the problem is the Closest point returns too many values, not equal to the number of points in the intersection. My surface started as a mesh that I imported from Revit, and then converted to a…"

How to find normals at intersection of a curve and surface?

Hi all, interesting problem here.I have a grid of points, which define lines going down in the Z direction. I then find the intersections of these with a topographical surface below (a Brep, collection of surfaces). How can I find the normals at these intersections, so that if I distribute a planar object to these points they will orient to the topography? I have tried Surface CP, and Evaluate Surface, but they return results for each surface in the Brep, not at the specific…See More

"Hi JP,From what you said, this is what you need: There is just one problem: In order for attractor/repeller to work correctly it needs to have the same number of objects scales, as objects . But you want to have less object scales than actual…"

Removing items from a list by Smalller Than

Hi guys,Relative noob to Grasshopper here (I'm taking an intro course at university right now, but still in the dark on a lot of how this works). I'm working on an attractor pattern, and would like to filter a list to remove items that equal 1. For example, I have remapped a list which determines the scale of my 690 objects (from 0.1 - 1.0), and I want to disclude all of the 1.0s. I stumbled upon the Smaller Than component, which gives me a True/False list, but I simply want my list to…See More
